I know at least one person - a very, very smart person - who really struggles in flipped classrooms. I think there are people who thrive in them and people who don't, and that axis is orthogonal to the gifted/not gifted axis.

Flipped classrooms look wonderful - here's a group of people who were struggling before, and look, they're thriving! But you can miss that here's another group who were thriving before, and now they're struggling.
